Air-to-water heat pump new build - single-family house with basement - model?

Building a house is simply not the same as buying a new television or refrigerator. Whereas even here, one sometimes spends days and weeks dealing with it.

Definitely... We are also very, very diligent and really read up thoroughly on all topics, which is why there is also the lack of trust.

It is just simply difficult to keep up with today's technical standards somehow. In the past, you just installed the oil heating system and that was it.

Today, you think about energy standards, ventilation systems, heat pumps in various types, and so on and so forth... Of course, it's all fun, no doubt, but I just feel poorly advised with so many points of contact. Sometimes even the construction companies are significantly less informed than I am as a layperson. That’s just annoying.

That’s why I wish for some good guidance here as well.

Construction companies all want to install the Viessmann Vitocal 200-S...

What do you think about that?

Look at the COP values of the Viessmann at A-7 to A 7 and compare them with the Wolf CHA 07. Which 200 do they want to install, that is just the series.

Unfortunately, we are still far from the model

I thought one might be able to make statements here about whether the Wolf CHA 07 is generally better than the 200-S from Viessmann.
